QueryItem

Struct QueryItem 

Source
pub struct QueryItem<'a> { /* private fields */ }
Expand description

A single query result item

§APIs

QueryItem only has data type APIs like get_str() instead of directly get_filename(), etc. This is mainly for symmetric APIs: in query() you need call request_flags() with needed RequestFlags, requiring the same RequestFlags for getting the data will make the code symmetric and eaiser to read.

A fully type-safe API may be added in the future if it won’t blow up the compile time.

Implementations§

Source§

impl QueryItem<'_>

Source

pub fn get_ptr(&self, flag: RequestFlags) -> Option<*const u8>

Get raw data pointer for a request flag

Source

pub fn get_str(&self, flag: RequestFlags) -> Option<&U16CStr>

Source

pub fn get_string(&self, flag: RequestFlags) -> Option<String>
